HANGING LAMP.

SPECIFICATION forming part of Letters Patent No. 467,462, dated. January19, 1892.

Application filed November 17, 1890. Serial No. 371,738. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE BOHNER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Hanging Lamps, of whichthe following ,is a specification. This invention relates to that typeof hang- 1mg lamps in which the fountis inserted from the under side ofand attached to the fountsupporting ring of the harp or lamp-supportingframe, the object of the present invention being to provide, inconnection with a diametricallyopposite inwardlyprojecting fixed ledgeor lug on the fount-supporting ring, a strong and durable automaticlatch mechanism, whereby the operation of inserting the lamp-fount isrendered easy and convenient, the holding of the fount in place renderedfirm and substantial, and a possibility of accidental detachmententirely avoided. I attain such object by the construction andarrangement of parts illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a lamp-fount and the lower portion ofthe harp or holder therefor, the fountsupporting ring being shown insection; Figs. 2 and 3, detail plan views of opposite sides of thefount-support- 1ng ring, and Fig. 4 an enlarged vertical sectionillustrating the spring-latch mechanism in its two positions.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the lower portion of thehanging-lamp frame or harp, to the extreme lower end of which is securedthe horizontal fount-supporting ring ,9, the inner and upper marginaledge of which is made overhanging to form an annular ab utment for thecircumferential bead 3 on the lamp-fount 4 in the usual manner.

5 is a fixed inwardly-projecting ledge or lug on the under side of thering 2, upon which one side of the lamp-fount is supported by means ofits circumferential bead 3.

6 is a vertically-arranged latch-piece, the lower end of which ispivoted at a point diametrically opposite to the fixed lug or ledge 5 bymeans of pendent brackets 7 on the ring,

2, the space between the brackets and an extension thereof up throughthe body of the ring 2 forming a receiving and guiding throat or slotfor the latch-bar, as shown. This latchpiece is preferably of an anchorshape, the vertical member or shank 8 forming an operating thumb-piece,the inner fluke 9 a supporting-heel for the 1am p-fount, and the outerfluke 10 a stop to abut against the under side of the ring 2, as shown,to limit the downward movement of the supporting'heel 9 in use.

11 is a suitable spring attached to the ring 2, with its free endbearing against the latchpiece 6 to force it inwardly to its engagingposition. It is evident, however, that the same result may be obtainedby gravity, and the same is within the province of the presentinvention.

lVhile the anchor formation of the, latchpiece 6, as shown anddescribed, is preferred on account of its simplicity and effectivestrength, it is, however, within the province my invention to modify theparticular construction of the same-as, for instance, bythe omission ofthe stop-heel 10 altogether-and forming instead a stop on the ring 2 forlim iting the inward movement of the vertical thumb-piece 8, as well asother equivalent modifications that would naturally suggest themselvesto parties skilled inthe art.

Having thus fully described my said invention, what I claim, and desireto secure by Letters Patent, is

1. A fount-holder for hanging lamps, comprising, in combination, afount-snpporting ring formed with pendent brackets 7, a vertical guideslot or throat, a fixed supporting lug or ledge 5, a vertically-arrangedlatch-bar 6, having an inwardly-projecting point or catch 9 and pivotedat its lower end in the pendent brackets '7, with itsupwardly-projecting end forming a thumb-piece, the shank of which isguided by the slot in the ring 2,and means for limiting the inwardmovement of said shank, substantially as set forth.

2. A fount-holder for hanging lamps, com prising, in combination, afount-supporting ring formed with pendent brackets 7', a vertical guideslot or throat, a fixed supportinglug or ledge 5, and avertically-arranged latchbar 6, having an inwardly-projecting point orcatch 9 and an outwardly-projecting point or stop 10, said latch-barbeing pivoted at its lower end in the pendent brackets 7, with itsupwardly-projecting end forming a thumbpiece, the shank of which isguided by the guide-slot in the ring 2, substantially as setforth.

3. A fount-holder for hanging lamps, comprising, in combination, afount-supporting ring formed with pendent brackets 7, a vertical guideslot or throat, a fixed supporting lug or ledge 5, a vertically-arrangedlatch-bar 6, having an inwardly-projecting point or] catch 9 and anoutwardly-projecting point or stop 10, said latch-bar being pivoted atits lower end in the pendent brackets 7, with its upwardly-projectingend forming a thumbpiece, the shank of which is guided by the guide-slotin the ring 2, and a spring 11,

adapted to force the latch-bar inwardly, substantially as set forth.

In testimony whereof Witness my hand this 14th day of November, 1890.

GEORGE BOHNER.
